How is the Cultural Revolution a Human Rights Violation?

In the 1960's Chinese leader Mao Zedong felt that his power was weakening by the day, and the Soviet Union was leading China in the wrong direction. After the failure of the "Great Leap Forward" and the economic crisis afterwards, he tried to convince the youth to revive the revolutionary spirit and change China for the better, starting the Cultural Revolution.

When Zedong called for the younger generation to attack the older generations for their wrongful thinking and lack of revolutionary spirit, he was telling the people to violate the older generation's right to security of person.
